If a woman is induced abortion, or is pregnant again on 10 day after drug abortion, it can only show that ovulation recovery time is relatively fast. Biochemical pregnancy also belongs to abortion, but it will become recessive abortion. Because the ovary will ovulate naturally after biochemical pregnancy, it may ovulate again after abortion 10 day, so if the same room does not use contraception, it will lead to pregnancy again. It is suggested to go to a regular hospital for ultrasound examination of uterus and appendix to determine drug abortion after intrauterine pregnancy.
